MACHINE FOR WINDING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 454,145, dated June 16,1891.

. Application filed October 25, 1886. Serial No. 217,153- (No model.)

To 612% whom it may concern:

Be it known that I, MARVIN O. STONE, of Washington, in the District ofColumbia, have invented certain Improvements in Machines for WindingPaper Tubes, of which the following is a specification.

This invention hasreference to a machine for winding together articlesfrom paper or equivalent sheet material, being more particularlydesigned, however, for the formation of cigarette and cigar holders oftubular form, with their ends waxed or otherwise rendered water-proof.

It is the particular aim of the invention to provide a machine by whichthe blanks may be rapidly wound into form, coated with wax, anddischarged, the whole operation, except the feeding of the blanks, beingautomatic.

The machine is of the same general character as that represented in myapplication for Letters Patent of the United States filed on the 5th dayof August, 1886, No. 210,152, but is modified in various minor detailsand provided with various additional features not contained in theoriginal machine.

In the accompanying drawings, Figure 1 represents a top plan view of myoriginal machine. Fig. 2 is an elevation of the same Viewed from theleft. Fig. 3 is an elevation of the same viewed from the right. Fig. 4is a transverse vertical section on the line 00 :0, Fig. 1, showingparticularly the waxing device. Fig. 5 is a cross-section on the line 2,Fig. 1, showing particularly the strippers by which the finished articleis automatically delivered. Fig. 6 is aside elevation showing the formof the spindles and the arrangement of the waxing device thereunder.

Referring to the drawings, A represents a rigid bedplate arranged,preferably, Man inclined position. In a stationary bearing on this frameI mount the journal of a tapered winding-spindle B, such as shown inFig. 6, and immediately beneath this spindle I mount a second taperedspindle 0, having its journal mounted, as shown in Figs. 3 and 6, on ahorizontal pivot, so that it may be thrown downward away from thespindle B, for purposes hereinafter explained. The two spindles havetheir; journals connected by pinions at, and may receive motion througha beveled pinion 12 from a gear-wheel c, mounted on a horizontal shaft(1 in fixed bearings on the frame, this arrangement serving to drive thetwo spindles at equal speeds and toward each other. Adjacent to thespindles and on a level with the space between them is mounted afeed-table D, 'on which the paper blanks are placed, and from which theyare fed, one at a time, corner-wise between the winding-spindles. Thetable is secured by an adjusting-screw c, passing through a slottherein, so that the table may be adj ust ed horizontally as the form ofthe blanks may demand. On its upper surface the table is provided with aflange f, againstwhich the edges of the blanks are pressed and by whichthey are directed in the proper direction as they enter between thespindles. The flange f iscurved longitudinally, as shown, so that as theblanks pressed edgewise against it are moved toward the tapered spindletheir path or course of movement is changedthat is to say, they areadvanced in a curved line as is required in the formation ofcigarette-tips and similar conical articles. The upper spindle is nearlyencircled, as shown particularly in Fig. 4, by a shield or guide passingdownward 011 the rear side close to the surface of the lower spindle andserving to turn the edge of the advancing blanks upward in order thatthey may be certain to wind around the upper instead of the lowerspindle. This guard is divided, as in my previous machine,longitudinally into two parts separable from each other and from thespindle in order to permit the removal of the finished tube. The lowerportion 1 is attached to the bearing of the lower spindle and movesdownward therewith. The upper portion 2" is attached to a lever j,pivoted midway of its length and urged downward by a spring It, as inFig. 4. The opposite end of this lever is connected by a link m to a second lever or, acted upon at its opposite end by alever 0, which is inturn pivoted near its middle to the frame and acted upon at its rear endby a crank pin or Wrist p. This crank-pin is carried by a disk on ashaft F, mounted in bearings on the main frame. The lever 71 is fixed tothe pivoted bearing of the lower spindle. Vhen the crank-pin 19depresses the lever o and operates the lever n, the latter serves tothrow the lower spindle ICO and the lower section '2'- of the guide awayfrom the upper spindle, and also serves, through the connection m oflever j, to lift the upper section 1' of the guide away from 5 the upperspindle, the result of this action being, as in the previous machine, touncover and expose the upper spindle, so that the finished article maybe stripped endwise therefrom.

For the purpose of discharging the finished article I provide twostrippers G and II, which act successively, the first to start the tubeforcibly from its place, and the second to expel the loosened tubequickly from the machine. The first stripper consists of an angularfinger pivoted near its middle to a supporting-arm I and connected to aspring J, by which its opposite end is caused to bear snugly on top ofthe upper spindle and to follow down closely on the upper surface ofthis spindle in the act of removing the tube therefrom. The bar I isarranged to slide in suitable bearings in a direction parallel with theaxis of the spindle. Itis drawn rearward 2 5 to maintain the stripper Gat the larger end of the spindle and out of the way of the incomingpaper by arod L, connected to an elbow-lever M, which latter is pivotedto the frame and provided at its opposite extremity 0 with a rollerbearing on a cam-disk N on. the shaft I before referred to. This diskhas its circumference of circular form and concentric to the axis,except at one point, where it is cut inward to release the lever Mmomentarily. A spring 0, fixed to theframe,acts upon the ejector-slide Iand tends con stantlyto urge the same forward,so that when thedepression in thedisk arrives at the end of the leverN and releases theparts the spring acts to drive the ejector 4o constantly forward. Thesecond ejector His simply a slide mounted in bearings in the frame, itsforward end arranged to slide between the two WindingSpi'ndles and itsrear end connected by a rod P to an angular lever 5 Q, which is pivotedon the main frame and arranged to be operated by a cam-disk R. A springT, connected with the ejector I, serves to throw it quickly forward,when its controlling-lever is released by the cam. As before mentioned,the second ejector acts immediately after the first, and advancingbeyond the point at which the first stops follows up theblank, insuringits delivery from the spindle. Motion is communicated to the machine iby a driving-wheel S, applied to the shaft (1,

from which motion is communicated by a pulley U, fixed thereon through abelt to a pulley V on the shaft F. I

For the purpose of automatically treating the blanks withparaffine,'wax, or other material previous to their delivery, I arrangethe lower spindle directly over a box or receptacle V, which receivesthe liquid material through a tube X from a melting-pot or res- 6 5ervoir Y, subject to the action of a gas-flame or other appropriatemeans of heating the same. This reservoir is supported on anadjusting-screw Z, by which its height may be regulated, and thus thelevel of the fluid in the chamber \V controlled, as required.

In order that the wax may be applied to the smaller end only of the tubeor smoker, the rear end of the lower spindle Cis reduced in diameter, asshown in Fig. 6. This prevents the wax or paraliine from finding its wayonto the rear end of the spindle, whence it would pass to the paper.

It will be observed that the reduction in the diameter of spindle Oceases near its rear or larger end; or, in other words, that it is leftof full diameter at its rear end beyond the box IV, so as to bearagainst the end of the paper tube and confine the same against thewinding-spindle.

I do not claim, broadly, herein a spindle C cooperating with thewinding-spindle and the wax-receptacle and mounted to advancealternately to the said winding-spindle and receptacle, the same formingpart of my prior application, above referred to. The present inventionin this regard is limited to the spindle C in the peculiar form hereinshown, its two ends adapted to bear upon the tube on the winding-spindleand one end reduced to prevent the transfer of the wax or other materialthereby, combined with the windingspindle and reservoir.

\Vhen necessary, in order to prevent the chilling of the wax by contactwith the spindles, I provide a special flame, as shown at a, to heat theparts adjacent to the spindles; or a rigid arm may be extended from theframe which supports the spindles to the flame which melts the wax,transmission of heat through this arm serving to keep the frame andspindles at a sufiiciently high temperature to prevent the wax fromchilling.

\Vhile I have represented a machine particularly adapted for theformation of tapered smokers or mouth-pieces, it is to be understoodthat spindles of any suitable length and of any suitable form may beused in order to adapt the machine for the formation of other tubulararticles from paper.

In using the machine as represented in the drawings, the blanks arepasted at one edge previous to their passage between the rolls; but itis to be understood that, although I lay no claim thereto in the presentapplication, I may use automatic devices for pasting the blanks andfeeding them into the machine represented herein.

Having thus described my invention, what I claim is-- 1. In a machinefor winding tubular paper articles, the winding-spindle, in combinationwith two strippers or ejectors acting successively.

2. In combination with the winding-spindle, the stripper G, arranged totraverse its rear end, and a second stripper arranged to advance beyondthe stripper GF.

3. In combination with the winding-spindle, the two strippers, springsurging said strippers forward, and two retracting-cams connected bylevers and suitable intermediate devices with the respective strippers.

4. In combination with the winding-spindle B and a sliding bar I, thestripper G, movably attached to said bar, and a spring acting to holdthe stripper in contact with the surface of the spindle.

5. In combination with the spindles B and O, the reservoir beneaththelatter, and the melting-pot connected with the reservoir,substantially as described.

6 In combination with the waxing-spindle C, the reservoir thereunder,the melting-pot connected with the reservoir, and means, substantiallyas described, for adjusting the melting-pot vertically.

7. A tapered winding-spindle, in combination with a feed-table providedwith a ledge or flange f, curved, substantially as described,

to direct the blanks at a changing angle to the spindle.

8. In combination with the tapered windingspindle,the horizontally-adjustable feed-table D, provided with a curved guard or flange f.

9. In a machine for forming and coating paper tubes,the combination ofthe rotary wind ing spindle, the reservoir W for the coating material,and the intermediate movable spindle 0, having the reduced portionextended from a point near the middle nearly to the rear end, butterminating short of said end, whereby it is adapted to apply thecoating material to one end of the paper tube and to apply pressure toboth ends of the same.

In testimony whereof I hereunto set my hand this 20th day of 0ctober,1886, in the presence of two attesting witnesses.
